• Online Capacity Expansion is officially supported for RAID levels 0, 5, 6, and 10 by adding additional disks.
• Although not officially supported, see the following slide for what is technically possible for Adaptec 5, 6, 7, and 8 series RAID controllers. Internal tests were conducted in lab environments; not recommended for live production environments.

• It is also technically possible to increase the size of a RAID 1 or 10 array by replacing existing drives with larger capacity drives, one by one, until all disks have unused, free space. Simply right-click a logical device (array) and choose 'Expand or change logical device'.

  Please ensure you have a FULL BACKUP before attempting OCE or RLM.
